How it works

The same technology that powered Apollo and the Space Shuttle — on your wall.

Redde watches and waits

Monitors your battery around the clock. If it doesn’t need a top-off, Redde doesn’t run.

Battery needs a top-off

When the battery dips below a set threshold, Redde quietly turns on, recharges it, and powers down.

"We live close enough to our neighbors that a generator was never really an option. This runs so quietly, most of them don't know we have backup power at all."

Going Off-Grid? Stay powered with Redde

Solar and batteries can take you off the grid. Redde keeps you there. When days of clouds leave solar unable to keep up, Redde automatically recharges your battery using propane already on site, so reliable power doesn’t depend on the weather (or a loud standby generator).

“I love my Redde fuel cell generators. They run off of the propane that I already have delivered to my house, and they only use a tiny amount of fuel to keep my battery system charged when the solar panels aren’t producing enough electricity."

"It's extremely low maintenance, and the efficiency is impressive. Depending on the season, it handles my whole home's power needs."
Jamison W.

"It uses a tiny amount of natural gas and automatically tops up our batteries so we can keep our whole home running no matter the weather or wildfire situation. We recommend this generator to all of our neighbors!"
